Threats Tagged 'mal-2026-6786'

The @marketfront/mychatspreloader npm package version 7.0.0 is part of a malicious campaign involving 25 packages published within a short time frame. It contains a heavily obfuscated postinstall script that executes automatically during npm install, harvesting sensitive credential files from the user's system. The stolen data includes SSH keys, AWS credentials, Kubernetes configs, Docker configs, npm tokens, Git credentials, environment files, and shell history. The collected information is exfiltrated via encrypted HTTPS POST requests and DNS tunneling to a concealed command-and-control server. The package has no legitimate functionality and is designed solely to steal credentials under the guise of an internal scoped package. This campaign shares infrastructure and tactics with a previous malicious npm campaign, indicating a recurring threat actor.
